I need to put a very heavy bathroom mirror on a platerboard wall. The mirror has 4 holes for screws. As suggest on your website, I am usingRedidrive plug (metal) for the screws, but I dont think these would be enough as the mirror is very heavy. Someone suggest to use adhesive behind the mirror. Will that work? I have bought EVO-STIK WET GRAB WATERPROOF adhesive. Is this the strongest? Please help. Thanks vm.

We would be a bit surprised if the Redidrive didn't hold it as we have used them for microwaves and bookshelves for years but if you want to be sure who can blame you. The strongest of all construction adhesives is called Gripfil (see the adhesives used at home project) but the wet grab is also good stuff.

Thanks vm. I was concerned becoase it feels like my plaserborad wall is not very strong. when I screwed in the Redidrive screw was coming aprat. I have now put some adhesive around it. lets hope it works.
